Collection
Invictus Valour Solid-State DACs
Solid-state, transistor-based instruments built for natural timbre.
Prometheus
A window filter in programmable logic
PCM is converted to DSD on the chip and passed through a logic-based window filter, with no LC output filter.
Hyperion
Unhurried
The Cirrus Logic CS4397: an expressive midrange, a deep and controlled low end, decays left to fade on their own.
Bellerophon
A converter and an amplifier
A DAC and a Class AB amplifier on Toshiba bipolar transistors, in one classic chassis.
Invictus Valour
A human nature
Natural timbres and a living sound: the qualities of a human being rather than of a god.
About the collection
The Invictus Valour collection: Prometheus, Hyperion and Bellerophon, solid-state DACs voiced for natural timbre and a living sound, built by hand to order.
Invictus means not only invincible or unconquerable but, above all, unbending and unshakeable. Valour is courage and fearlessness, and with them fortitude: the qualities of a human being rather than of a god.
Hence the names of these instruments: each belongs to a hero who fought monsters and gods. Solid-state and built on transistors, they aim at natural timbre and a living sound.
